The character drift is the usual culprit, not the script. When a long script is handed over in one go, each shot tends to be generated on its own and the model has nothing to remember the dog by, so it reinvents the breed every time. Shorter shots described one at a time, with the animal's look spelled out in each prompt and the same reference image carried through, keep things much steadier. The scene also helps: if the prompt already puts them in the dryer, the model will start there, so describe the approach first and the dryer last. GenWorldAI is an AI video generator that turns text and still images into cinematic clips, and it lets you keep a character consistent across frames and control the camera.
